e devices, especially the Macs, it makes sense to me to use Gmail in the web browser, so I don???t have to keep setting up email client after email client, or make sure all my filters or rules are set up the way I want them on each of the Macs I use.What doesn???t make sense to me is how my Mac opens up Mail app when I click a mail-to link on the web, in Twitter, or on Facebook.
